1-gogs: never worried too much about them. in reality, they are only a windshield. i spent $20 and never worried.
2-helmet: i never wore a helmet unless i was doing a RW jump. then they become incredibly important. closing speeds are a killer. google 'bonehead'. a SDU buddy of mine witnessed a bounce during the '96 WFFC in chicago. as i (dimly) recall, the jumper muffed a canopy xfer at about 300', and hit at 70-80mph. broke many, many bones, but not his brain bucket. i believe it was a 'bonehead' helmet. if i could have afforded one, i would have worn it for every jump.
3-rig: never, ever, ever impulse buy. if you do, you'll probably find the exact same gear at 60% of the price within a month. in '95, i picked up a used racer elite, PD 170 reserve, and a monarch135 ZP (non-elliptical) main for <$900. if i hadn't been patient, i would have spent DOUBLE that amount buying the same gear.
get to know the jumpers who are going for a new license. they'll be looking to sell their old gear. you'll want to look for guys going from a 'b' to a 'c'. get to know the riggers, as they will be a good source of info on this.
don't be afraid to buy components. if you find a good container at a great price, pick it up now, and wait on the canopy. remember that most jumpers go through canopies faster than containers. the possible exception is the new license-holder, who will be going to a much smaller canopy and much smaller container at the same time.
you're probably jumping a 300sqft canopy right now. look for a f111 (porous) 250. there are many manufacturers out there, but you can never go wrong with PD. (performance designs) don't worry about zero-porosity right now. your DZ will probably not let you use it until you get your C license. then again, i used free booze to bribe my DZ mgr, and was jumping a sabre 150 on jump 30, so you never know.
as far as the container, you'll probably get the best deal on a racer elite. they look a bit awkward, but are significantly less expensive that a comparable talon, and the reserve deployment time is better. then again, those talons
are cool.
4-jumpsuit: who cares. until you start RW, you won't need to worry about your fall rate. i've jumped in jeans, bdus, shorts, and au naturelle. now, if you're going directly into RW, this'll get bumped up the priority list. at you're size, you'll fall pretty fast, so to be compatible with most RW fun jumpers, you'll want the suit to be a little loose. just make sure that it fits your height properly. if buying used, make sure that the holds are secure, and the bootie snaps work properly. these HURT when they come open and bang into your leg at terminal.
please note that it is
very important to write 'place parachute here', along with a large X, on the back of your jumpsuit. i got more pity jumps that way...
i'd prioritize expenditure for gear as follows:
1. container/reserve. (as good as you can possibly afford)
2. altimiter. (same)
3. main.
4. everything else.
after the main, i'd go cheap on everything else and save your money for a cypress, but that's just me, and i'm no expert.
blue skies!
